This is hopefully end of duplication. This batch did not cause clashes
in Sphinx but it was pointless nonetheless as we have auto-generated
anchors for all statements.
Some statement names like "allow-query" had manually defined link anchor
_allow-query and also implicit anchor created by
.. namedconf:statement:: syntax. This causes warnings if a ambiguous
reference is made using :any:`allow-query` syntax.
Remove (hopefully all) manually defined anchors which pointed to
identical place as the implicit anchor. This allows :any: to work.
In rare cases where manual anchor points to descriptive text separated
from statement definition the reference was disamguated by replacing
:any:`notify` with :ref:`notify` (for manual anchor)
vs. :namedconf:ref:`notify` (for statement definition).
Please note that `options` statement is a trap: It is ambiguous even
without manual anchor because rndc.conf has its own `options`. Use
:namedconf:ref:`options` vs. :rndcconf:ref:`options` to select
appropriate target.
It turns out that many manual edits were required:
- Heading underlines were too short because :any:`` is longer than ````
- Some statement names clashed with manually defined _link_anchors
(notify, trust-anchors etc.)
- Zone types are defined like "type primary" in the internal grammar and
that caused mayhem in the replacement script as it took "type" and
individual types ("primary", "secondary") as separate statements.
For that reason :any:`primary` had to be manually replaced with
:any:`primary <type primary>` where appropriate.
- Sometimes option name is also the same as a value name (e.g. "notify")
and then it did not make sense to do the replacement.
